KEY-OPENING on.

Application filed January 15, 1923. Serial No. 612,602.

To all whom it may concern:

Be it known that I, JOHN M. YoUxG, a

citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Key-Opening Cans, of

which the following is a specification.

My invention relates to an improvement in key opening cans intended primarily to provide a suitable means of retaining the key upon the can prior to use, while also permitting ready removal by the customer.

To this end, the invention contemplates the provision of a key having a suitable part thereof welded to the can and notched, or otherwise weakened, adjacent the point of welding whereby it may be readil removed by a fracture at the notch.

Other objects and advantages of the invention will besapparent as itis better understood from *the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof. 1

Referring to the drawings,

Figure 1 is a perspective view of a key opening can having a key attached thereto in accordance with my invention;

30 Fig. 2 is a plan view thereof with the key 4 in normal attached position; and

Figs. 3 and .4 are similar views showing the different ositions of said key as it is being removed: 1

I have shown on the drawings, for the purpose of illustrating my invention, a can havlng a cylindrical body'll with the usual bottom .12 and cover 13 permanently attached thereto by a double seam, or other hermetic joint. A tearing stri 14 is set oil in the cylindrical body 11 y means of parallel score lines 15 and 16. Said strip is provided with an extension, or tongue, 17 adapted to be engaged by a slotted key upon away. Said tongue preferably takes off from the body at the side seam 18 in which which the strip may be wound as it is tornwelding holds it firmly in place. Adjacent the spot weld, the key wire is notched, as at 24. and thus weakened so that pressure applied to the body, to turn it upon the cover, readily fractures the wire at the notch and the key is thus removed foruse. This action is clearly illustrated in Figs. 3 and 4. from which it will be seen that the notch is first widened, as shown at 25 in Fig. 3,

and then the wire is severed as'shown in Fig. .4. leaving the welded portion 26 attached to the cover.

Since the key is firmly held in fiat con-- dition against the cover, which has an outer upstanding rim 27, it is protected against accidental removal and still may be readily broken away by moderate pressure applied in the right manner by the user. Thus it will always be present when needed, with no attendant difliculties in removing it for use.

It is thought that the invention and many of its attendant advantages will be under: stood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of-the' parts without departing from the spirit and scope of the invention,

or sacrificing all of its material advantages,

the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A key opening can, having a key welded thereto, said key being notched beyond the pointof welding whereby it may be removed by fracture of the notch.

2. A key opening can, having a key welded thereto, said key being notched adjacent the point .of'welding whereby it may be removed by fracturing pressure exerted atan angle to the notch.

3. A key opening can. and a keyfixedly secured thereto at a given point in the key body, the material of said key being weakened adjacent said pointwhereby the key may be broken away for use.

4. A key opening can, and a wire key having an end portion thereof spot welded thereto. the wire being cut away near the point of weld and readily severable by pressure exerted by the hand.

5. A key opening .can, and a wire key formed with a tongue-engaging body and a head portion curved to an extremity adjacent said body, said extremity being flata key having an end ortion welded to said tened and welded to the can cover and the cover, the material 0 said vkey being Weakmaterial adjacent said Welded extremity beened adjacent the point of Weld and adapt- 10 ing notched whereby it may be fractured ed to be fractured by moderated turning. 5 by rotary pressure on the body of the ke pressure applied to the key.

6. A key opening can, comprising a body provided with a tearing strip, a cover, and JOHN M.- YOUNG.
